Requirements
Preconditions for smooth, vibration-free operation:
● Stable foundation design as per DIN 4024
● Precision alignment of the motor
● Correct balancing of parts to be fitted to the shaft end.
● ISO 10816-3-compliant vibration velocity
Proceed as follows
● Use machine fixing bolts with the necessary strength class to ISO 898-1 (e.g. 10.9) for
● When selecting the bolts and the design of the foundation, take into account the

Balance quality
The rotors are balanced dynamically. For shaft extensions with featherkeys, the balancing
type is specified using the following coding on the face of the drive end of the shaft:
● "H" means balancing with a half feather key
● "F" means balancing with a whole feather key.

in phase opposition. The values for the foundation forces can be found in the configuring
documentation or are available on request from the manufacturer.
NOTICE
System-inherent frequencies
If the foundation has not been constructed correctly, frequencies that are inherent to the
foundation can occur after the machine set has been installed (system-inherent
frequencies). This can damage the machine set.
DIN 4024 must be taken into account when constructing the machine foundation.
